Dorian b827f89dcd fix: serve SPA from apps/web/dist (matches server default) + use Datum IP
Two production-blocker bugs from the first deploy:

1. Static SPA never served — Dockerfile copied apps/web/dist into
   apps/api/public, but server.ts default static dir resolves to
   apps/web/dist. Mismatch meant every route fell through to Express'
   bare 404 ("Cannot GET /"). Aligning Dockerfile to the default path.

2. DNS for the Datum container name failed (getaddrinfo ENOTFOUND
   datum_datum_1) — gashboard's Docker DNS doesn't reliably alias
   external-network container names across compose stacks. Switch the
   default DATUM_URL to the container's known IP on umbrel_main_network
   (10.21.0.11, captured during earlier diagnostics). If the IP changes
   the user can override DATUM_URL in env. If gashboard isn't actually
   joined to umbrel_main_network, the next failure will be a much more
   diagnostic ECONNREFUSED instead of an opaque ENOTFOUND.
